In step S402, the approach detection unit 304 decides whether or not anemergency vehicle has approached the vehicle 10. For example, theapproach detection unit 304 detects the approach of the emergencyvehicle by means of a rotary lamp of the emergency vehicle detected fromimage data which is acquired by imaging the vicinity of the vehicle 10by the image acquisition unit 302, a siren sound detected from sounddata in the vicinity of the vehicle 10 which is acquired by themicrophone 140, or the like. Alternatively, the approach detection unit304 may detect the approach of the emergency vehicle based on vehicleinformation and the like acquired from another vehicle in the vicinityof the vehicle 10 by the vehicle-to-vehicle communication device 150.

In a case where the approach of the emergency vehicle is detected, theon-vehicle device 110 makes the processing proceed to step S403. On theother hand, in a case where the approach of the emergency vehicle is notdetected, the on-vehicle device 110 repeatedly executes the process ofstep S402.

When the processing proceeds to step S403, the first decision unit 306decides whether or not a point where the vehicle 10 is traveling is inthe vicinity of an intersection. For example, the first decision unit306 decides whether or not the point where the vehicle 10 is travelingis in the vicinity of an intersection by using positional information onthe vehicle 10 which is acquired by the positional informationacquisition unit 307 and road information which is stored in the mapinformation DB 308.

In a case where the point where the vehicle 10 is traveling is in thevicinity of an intersection, the on-vehicle device 110 makes theprocessing proceed to step S404. On the other hand, in a case where thepoint where the vehicle 10 is traveling is not in the vicinity of anintersection, the on-vehicle device 110 makes the processing proceed tostep S405.

When the processing proceeds from step S403 to step S404, the evaluationunit 310 sets an evaluation standard in a case where the vehicle is atan intersection to be described later, as an evaluation standard usedfor the evaluation of the driver's driving manner.

When the processing proceeds from step S403 to step S405, the firstdecision unit 306 decides whether or not the point where the vehicle 10is traveling is on a one-way road. For example, the first decision unit306 decides whether or not the point where the vehicle 10 is travelingis on a one-way road by using the positional information on the vehicle10 which is acquired by the positional information acquisition unit 307and the road information which is stored in the map information DB 308.

In a case where the point where the vehicle 10 is traveling is on aone-way road, the on-vehicle device 110 makes the processing proceed tostep S406. On the other hand, in a case where the point where thevehicle 10 is traveling is not on a one-way road, the on-vehicle device110 makes the processing proceed to step S407.

When the processing proceeds from step S405 to step S406, the evaluationunit 310 sets an evaluation standard in a case of one-way traffic to bedescribed later, as an evaluation standard used for the evaluation ofthe driver's driving manner.

When the processing proceeds from step S405 to step S407, the evaluationunit 310 sets an evaluation standard in a normal case to be describedlater, as an evaluation standard used for the evaluation of the driver'sdriving manner.

In step S408, the evaluation unit 310 performs the evaluation of thedriver's driving manner in accordance with the evaluation standards setin steps S404, S406, and S407. For example, the evaluation unit 310performs the evaluation of the driver's driving manner in accordancewith the evaluation standards set in steps S404, S406, and S407 in anevaluation standard 610 as illustrated in FIG. 6A. As described above,the evaluation unit 310 according to the embodiment performs theevaluation of the driver's driving manner by using different evaluationstandards in accordance with decision results of the first decision unit306.

FIG. 6A illustrates an example of the evaluation standard 610 used forthe evaluation of the driver's driving manner. In the example of FIG.6A, the evaluation standard 610 includes information such as “largeitem”, “small item”, “case of intersection”, and “normal case”. Theinformation in “large item” indicates evaluation items, such as hazard,deceleration, avoidance, and stop, which are used for the evaluation ofa driving manner. The information in “small item” indicates evaluationcontents and the like of each evaluation item.

The information in “case of intersection” indicates an evaluationstandard 611 in a case where the vehicle is at an intersection. Theinformation in “case of one-way traffic” indicates an evaluationstandard 612 in a case of one-way traffic. The information in “normalcase” indicates an evaluation standard 613 in a normal case other thanthe case of intersection and the case of one-way traffic.

The evaluation items and the evaluation standards which are included inthe evaluation standard 610 illustrated in FIG. 6A are examples. Forexample, regarding the evaluation standards used for the evaluation ofthe driver's driving manner, some of the evaluation items (or evaluationstandards) may be different from those of the evaluation standard 610illustrated in FIG. 6A, as shown in an evaluation standard 620illustrated in FIG. 6B.

FIG. 5 is a flowchart illustrating an example of a driving mannerevaluation process according to the first embodiment. The process showsan example of the driving manner evaluation process executed in stepS408 of FIG. 4.

In step S501, the determination unit 309 determines whether or not thevehicle 10 has flickered a hazard lamp, and notifies the evaluation unit310 of determination results. For example, the determination unit 309determines whether or not the vehicle 10 has flickered a hazard lamp byusing traveling information acquired by the traveling informationacquisition unit 305 when the approach of the emergency vehicle has beendetected by the approach detection unit 304.

In step S502, the determination unit 309 determines whether or not thevehicle 10 has performed deceleration, and notifies the evaluation unit310 of determination results. For example, the determination unit 309determines whether or not the vehicle 10 has performed deceleration byusing the traveling information (for example, speed information,acceleration information, and the like on the vehicle 10) which isacquired by the traveling information acquisition unit 305 when theapproach of the emergency vehicle has been detected by the approachdetection unit 304.

In step S503, the determination unit 309 determines whether or not thevehicle 10 has performed avoidance and determines contents of theexecution of the avoidance, and notifies the evaluation unit 310 ofdetermination results. For example, the determination unit 309determines whether or not the vehicle 10 has performed avoidance byavoidance determination processing to be described later. In a casewhere avoidance has been performed, the determination unit 309determines whether or not avoidance has been performed within anintersection and whether left-justified avoidance has been performed atthe front of the intersection, as the contents of the execution of theavoidance.

In step S504, the determination unit determines whether or not thevehicle 10 has stopped, and notifies the evaluation unit 310 ofdetermination results. For example, the determination unit 309determines whether or not the vehicle 10 has stopped by using thetraveling information (for example, speed information on the vehicle 10)which is acquired by the traveling information acquisition unit 305 whenthe approach of the emergency vehicle has been detected by the approachdetection unit 304.

In step S505, the evaluation unit 310 performs the overall determination(evaluation) of the driver's driving manner by using the determinationresults notified from the determination unit 309 and the evaluationstandards set in steps S404, S406, and S407 of FIG. 4. For example, instep S404 of FIG. 4, it is assumed that the evaluation standard 611 inthe case of intersection as illustrated in FIG. 6A is set.

In this case, the evaluation unit 310 adds “1” to an evaluation score ina case where deceleration has been executed and does not perform theaddition of an evaluation score in a case where deceleration has notbeen executed, in accordance with whether or not deceleration has beenperformed. The evaluation unit 310 adds “1” to an evaluation score in acase where avoidance has been executed and subtracts “1” from theevaluation score in a case where avoidance has not been executed, inaccordance with whether or not avoidance has been performed. Theevaluation unit 310 subtracts “2” from the evaluation score in a casewhere avoidance has been performed within an intersection and adds “1”to the evaluation score in a case where left-justified avoidance hasbeen performed at the front of the intersection, in accordance withcontents of the execution of the avoidance. The evaluation unit 310 adds“1” to the evaluation score in a case where stop has been performed anddoes not addition to the evaluation score in a case where stop has notbeen performed, in accordance with whether or not stop has beenperformed.

The evaluation unit 310 can set the evaluation score having beensubjected to addition or subtraction, for example, by theabove-described processing, as evaluation results on the driver'sdriving manner.

Referring back to FIG. 4, the description of the flowchart illustratingan example of the processing of the on-vehicle device will be continued.

In step S409, the transmission unit 311 transmits evaluation informationincluding the identification information on the driver identified instep S401 and the evaluation results of the evaluation performed in stepS408 by the evaluation unit 310 to the server device 100 through thecommunication controller 301.

Desirably, the on-vehicle device 110 executes the process of step S409and then repeatedly executes the process of step S402 and the subsequentprocesses.

By the above-described processing, the on-vehicle device 110 evaluatesthe driver's driving manner when an emergency vehicle approaches thevehicle 10, and can notify the server device 100 of evaluation results.

Avoidance Determination Process 1

FIG. 7 is a flowchart illustrating an example of avoidance determinationprocessing according to the first embodiment. The processing is anexample of determination process in which the determination unit 309determines whether or not the vehicle 10 has performed avoidance in stepS503 of FIG. 5.

In step S701, the determination unit 309 acquires information on asteering angle from the traveling information on the vehicle 10 which isacquired by the traveling information acquisition unit 305.

In step S702, the determination unit 309 decides whether or not the sizeof the steering angle is equal to or greater than a threshold value.Here, regarding the threshold value, it is assumed that a value fordeciding that the vehicle 10 has performed avoidance is set in advance.

In a case where the size of the steering angle is equal to or greaterthan the threshold value, the determination unit 309 determines thatavoidance has been performed (execution of avoidance) in step S703. Onthe other hand, in a case where the size of the steering angle is notequal to or greater than the threshold value, the determination unit 309determines that avoidance has not been performed (non-execution ofavoidance) in step S704.

Although the above-described process is an example of the avoidancedetermination processing, the determination unit 309 similarlydetermines whether or not the flickering of the hazard lamp,deceleration, stop, or the like has been performed, by using thetraveling information acquired by the traveling information acquisitionunit 305.

The determination unit 309 may determine the flickering of the hazardlamp, deceleration, avoidance, stop, or the like by using image dataacquired by imaging the vicinity of the vehicle 10 by the imageacquisition unit 302.

Avoidance Determination Process 2

FIG. 8 is a flowchart illustrating another example of the avoidancedetermination processing according to the first embodiment. Theprocessing is another example of determination processing in which thedetermination unit 309 determines whether or not the vehicle 10 hasperformed avoidance in step S503 of FIG. 5.

In step S801, the determination unit 309 acquires information on asteering angle from the traveling information on the vehicle 10 which isacquired by the traveling information acquisition unit 305.

In step S802, the determination unit 309 detects, for example, a whiteline on the left side of a road by using the image data acquired byimaging the vicinity of the vehicle 10 by the image acquisition unit302.

In step S803, the determination unit 309 decides whether or not the sizeof the steering angle is equal to or greater than a threshold value. Ina case where the size of the steering angle is not equal to or greaterthan the threshold value, the determination unit 309 determines thatavoidance has not been performed in step S804. On the other hand, in acase where the size of the steering angle is equal to or greater thanthe threshold value, the determination unit 309 makes the processingproceed to step S805.

When the processing proceeds to step S805, the determination unit 309decides whether or not the vehicle 10 has extended over the white linedetected in step S802. In a case where the vehicle 10 has not extendedover the white line, the determination unit 309 determines thatavoidance (small) has been performed in step S806. On the other hand, ina case where the vehicle 10 has extended over the white line, thedetermination unit 309 determines that avoidance (large) has beenperformed in step S807.

As described above, the determination unit 309 may perform determinationprocessing by using image data to be acquired by the image acquisitionunit 302. The determination unit 309 may perform determination regardingavoidance by performing level classification into a plurality of levelsin accordance with, for example, the magnitude of deceleration, themagnitude of avoidance, or the like.

Real-Time Processing of Server Device

FIG. 9A is a flowchart illustrating an example of real-time processingof the server device 100. The processing is an example of real-timeprocessing executed when the server device 100 receives evaluationinformation from the on-vehicle device 110.

In step S911, the information management unit 322 of the server device100 executes the process of step S912 and the subsequent processes whenreceiving the evaluation information from the on-vehicle device 110through the communication controller 321.

In step S912, the information management unit 322 acquiresidentification information on the driver which is included in theevaluation information, and refers to evaluation results correspondingto the identification information on the driver which is stored in thedriving manner DB 324, that is, evaluation results on the driver'sdriving manner.

In step S913, the information management unit 322 decides whether or notthe number of evaluation results on the driver's driving manner whichare stored in the driving manner DB 324 is equal to or greater than apredetermined number. Here, regarding the predetermined number, it isassumed that a sufficient number is determined in advance in order todecide the driver's driving manner, for example, in a case where anaverage value of the evaluation results on the driver's driving manneris calculated.

In a case where the number of evaluation results is equal to or greaterthan the predetermined number, the information management unit 322overwrites the evaluation results included in the evaluation informationreceived in step S911 to the oldest evaluation results, among theevaluation results on the driver which are stored in the driving mannerDB 324, in step S914.

In a case where the number of evaluation results is not equal to orgreater than the predetermined number, the information management unit322 adds the evaluation results included in the evaluation informationreceived in step S911 to the evaluation results on the driver which arestored in the driving manner DB 324, in step S915.

By the above-described processing, when the information management unit322 receives the evaluation information from the on-vehicle device 110,the information management unit stores the latest data within thepredetermined number, among the evaluation results on the driver, in thedriving manner DB 324 to manage the data, based on the identificationinformation on the driver which is included in the evaluationinformation.

Batch Processing of Server Device

FIG. 9B is a flowchart illustrating an example of batch processing ofthe server device 100. The processing is an example of batch processingexecuted by the server device 100, for example, for each predeterminedperiod.

In step S921, the information management unit 322 of the server device100 starts to execute the process of step S922 and the subsequentprocess in a case where a predetermined period elapses from the previousprocess.

In step S922, the information management unit 322 refers to (acquires)evaluation results (first evaluation results) on the driver in apredetermined period (first predetermined period) which are stored inthe driving manner DB 324.

In step S923, the information management unit 322 calculates an averagevalue of the evaluation results on the driver in the predeterminedperiod which are referred to in step S922.

In step S924, the information management unit 322 decides whether or notthere is a difference between the average value of the evaluationresults on the driver in the predetermined period which are calculatedin step S923 and an average value of the evaluation results (secondevaluation results) on the driver before the predetermined period(second predetermined period). It is assumed that the informationmanagement unit 322 stores the average value of the evaluation resultson the driver which is calculated in the past process in a storage unitsuch as the driving manner DB 324 to manage the stored average value.

In a case where there is no difference between the average value of theevaluation results in the predetermined period and an average value ofthe past evaluation results, the information management unit 322terminates the batch processing. On the other hand, in a case wherethere is a difference between the average value of the evaluationresults in the predetermined period and the average value of the pastevaluation results, the information management unit 322 makes theprocessing proceed to step S925.

When the processing proceeds to step S925, the information managementunit 322 stores the average value of the evaluation results which iscalculated in step S923 in a storage unit, such as the driving manner DB324, as evaluation results on the driver, instead of the average valueof the past evaluation results which are stored in the storage unit andmanaged.

As described above, the information management unit 322 can maintainevaluation results on the safety related to the driver's driving in thelatest state. In a case where there is no difference between the averagevalue of the evaluation results in the predetermined period and theaverage value of the past evaluation results, the information managementunit 322 can further reduce a load of updating processing of theinformation management unit 322.

In step S926, the information association unit 323 transmits theevaluation results on the driver which are stored in the storage unit bythe information management unit 322 and identification information foridentifying the driver to an insurance company (for example, the serviceproviding system 330 or the like which is used by the insurance company)which provides an insurance service to the driver.

As described above, the insurance company providing an insurance serviceto the driver can give an incentive, such as a discount of a fee of theinsurance service provided to the driver, to the driver in accordancewith, for example, evaluation results on the driver's driving manner.

Second Embodiment

In the first embodiment, the on-vehicle device 110 performed theevaluation of the driver's driving manner by using, for example, theevaluation standard 611 in a case of intersection, the evaluationstandard 612 in a case of one-way traffic, and the evaluation standard613 in a normal case as illustrated in FIG. 6A, in accordance with apoint where the vehicle 10 was traveling.

For example, when the vehicle 10 is waiting for the light to change atan intersection, the flickering of the hazard lamp may not be neededdepending on a lane on which an emergency vehicle is traveling, such asa case where the emergency vehicle is passing through another lanedifferent from the driver's own lane.

In a second embodiment, the on-vehicle device 110 decides whether or notthe emergency vehicle is traveling on the driver's own lane or istraveling on another lane different from the driver's own lane, andperforms the evaluation of safety related to the driver's driving byusing evaluation standards varying depending on decision results.

Flow of Processing

Processing of On-Vehicle Device

FIG. 10 is a flowchart illustrating an example of processing of anon-vehicle device according to the second embodiment. Processes shown insteps S401, S402, and S409 among processes shown in FIG. 10 are the sameas the processes according to the first embodiment illustrated in FIG.4, and thus differences from the first embodiment will be mainlydescribed.

When the processing proceeds from step S402 to step S1001, the seconddecision unit 312 decides whether the position of an emergency vehiclecan be specified or is unclear, for example, by using image dataacquired by imaging the vicinity of the vehicle 10 by the imageacquisition unit 302. For example, the second decision unit 312 analyzesthe image data obtained by imaging the vicinity of the vehicle 10, anddecides that the position of the emergency vehicle is unclear in a casewhere the emergency vehicle, a rotary lamp of the emergency vehicle, orthe like is not detected.

In a case where the position of the emergency vehicle is unclear, theon-vehicle device 110 makes the processing proceed to step S1002. On theother hand, in a case where the position of the emergency vehicle is notunclear, the on-vehicle device 110 makes the processing proceed to stepS1003.

When the processing proceeds from step S1001 to step S1002, theevaluation unit 310 sets an evaluation standard in a case of unclearnesswhich is an evaluation standard in a case where the position of theemergency vehicle is unclear, as an evaluation standard used for theevaluation of the driver's driving manner. For example, the evaluationunit 310 can apply the evaluation standard 610 as illustrated in FIG.6A, as the evaluation standard in a case of unclearness.

When the processing proceeds from step S1001 to step S1003, the seconddecision unit 312 decides whether or not the position of the emergencyvehicle is on the driver's own lane (whether or not the emergencyvehicle is traveling on the same lane as that of the vehicle 10 or istraveling on a lane different from that of the vehicle 10). For example,the second decision unit 312 analyzes the image data obtained by imagingthe vicinity of the vehicle 10 to detect an emergency vehicle, a rotarylamp of the emergency vehicle, and the like, and decides whether or notthe emergency vehicle is traveling on the same lane as that of thevehicle 10 from a white line of a road, a traveling direction of theemergency vehicle, and the like.

In a case where the position of the emergency vehicle is on the driver'sown lane, the on-vehicle device 110 makes the processing proceed to stepS1004. On the other hand, in a case where the position of the emergencyvehicle is not on the driver's own lane, the on-vehicle device 110 makesthe processing proceed to step S1005.

When the processing proceeds from step S1003 to step S1004, theevaluation unit 310 sets an evaluation standard 1110 in a case of thedriver's own lane as illustrated in, for example, FIG. 11A, as anevaluation standard used for the evaluation of the driver's drivingmanner.

In the example of FIG. 11A, the evaluation standard 1110 in a case ofthe driver's own lane includes information such as “large item”, “smallitem”, “case of intersection”, and “normal case”, similar to theevaluation standard 610 illustrated in FIG. 6A. In FIG. 11A, theinformation of “case of intersection” indicates an evaluation standard1111 in a case of intersection in a case where the emergency vehicle istraveling on the same lane as that of the vehicle 10. The information of“case of one-way traffic” indicates an evaluation standard 1112 in acase of one-way traffic in a case where the emergency vehicle istraveling on the same lane as that of the vehicle 10. The information of“normal case” indicates an evaluation standard 1113 in a normal case ina case where the emergency vehicle is traveling on the same lane as thatof the vehicle 10.

In the example of FIG. 11A, a marking standard different from theevaluation standard 610 illustrated in FIG. 6A is set in the evaluationstandard 1110 in a case of the driver's own lane. For example, “timing”which is a small item is added to “deceleration” which is a large itemof the evaluation standard 1110 in a case of the driver's own lane.

When the processing proceeds from step S1003 to step S1005, theevaluation unit 310 sets an evaluation standard 1120 in a case ofanother lane as illustrated in, for example, FIG. 11B, as an evaluationstandard used for the evaluation of the driver's driving manner.

In the example of FIG. 11B, the evaluation standard 1120 in a case ofanother lane includes information such as “large item”, “small item”,“case of intersection”, and “other than case of intersection”. In FIG.11B, the information of “case of intersection” indicates an evaluationstandard 1121 in a case of intersection in a case where the emergencyvehicle is traveling on a lane different from that of the vehicle 10. InFIG. 11B, the information of “other than case of intersection” indicatesan evaluation standard 1122 in a case other than a case of intersectionin a case where the emergency vehicle is traveling on a lane differentfrom that of the vehicle 10.

As described above, in the embodiments, it is possible to decide whetherthe position of the emergency vehicle is on the driver's own lane or onanother lane or is unclear by the second decision unit 312, and theon-vehicle device 110 can set an evaluation standard varying dependingon decision results of the second decision unit 312.

In step S1006, the evaluation unit 310 performs the evaluation of thedriver's driving manner in accordance with the evaluation standards setin steps S1002, S1004, and S1005. For example, in a case where theevaluation standard in a case of the driver's own lane is set in stepS1004, the evaluation unit 310 performs the evaluation of the driver'sdriving manner by using the evaluation standard 1110 in a case of thedriver's own lane as illustrated in FIG. 11A.

For example, the evaluation standard 1110 in a case of the driver's ownlane illustrated in FIG. 11A includes the evaluation standard 1111 in acase of intersection, the evaluation standard 1112 in a case of one-waytraffic, and the evaluation standard 1113 in a normal case. In thiscase, the evaluation unit 310 executes, for example, the processes shownin steps S403 to S407 of FIG. 4, and performs the evaluation of thedriver's manner in accordance with the set evaluation standards.

In this case, the evaluation unit 310 can perform the evaluation of thedriver's manner by using different evaluation standards in accordancewith the decision result of the second decision unit and the decisionresults of the first decision unit.
